[PATCH v5 4/5] arm: mvebu: Support for 98DX25xx/98DX35xx SoC
Chris Packham
judge.packham at gmail.com
Fri Sep 23 03:31:38 CEST 2022
Add support for the Allecat5/Alleycat5X SoC. These are L3 switches with
an integrated CPU (referred to as the CnM block in Marvell's
documentation). These have dual ARMv8.2 CPUs (Cortex-A55). This support
has been ported from Marvell's SDK which is based on a much older
version of U-Boot.

Changes in v5:
- Minor fixup for checkpatch.pl complaint
Changes in v4:
- Remove unused mvebu_get_nand_clock() (will return in a later series)
- Remove unnecessary #ifdefs
- Misc style cleanups
- Replace CONFIG_MVEBU_SAR with simpler code implemented directly in
soc.c based around get_sar_freq which the 32-bit platforms already
use.
Changes in v3:
- Remove unnecessary dma-ranges property from ethernet nodes (mvneta now
correctly parses the property from the parent node).
- Keep soc_print_clock_info and soc_print_device_info local to
alleycat5.
